Objective To investigate the character and risk factors of coronary artery disease in prediabetes. Methods The 193 patients with coronary artery disease were divided into 3 groups according to the American diabetes associations (ADA) standard of diabetic diagnoses. (1) Normal glucose tolerance group(NGT group,122 cases). (2) Impaired glucose tolerance group (IGT group,39 cases). (3) Diabetes mellitus group (DM group,32 cases). All patients were checked by the coronary angiographic semiquantitative (CAG) and the 75g oral glucose tolerance test. Blood glucose, insulin, TG, TC, HDL C, blood pressure, BUN and Cr were determined. The coronary artery changes were analysed by CAG, and the severity of coronary artery stenosis were evaluated by AHA standards. The risk factors in coronary artery disease were analysed by pluralized straight line statistics. Results The coronary multivessel changes and the severity of coronary artery stenosis and calcification were more frequent in IGT group than in NGT group (66 5% vs 35 1%,8 9?3 6 vs 6 5?3 9,6 6?6 1 vs 3 9?4 1,P

Objective To study the characteristics and the related risk factors of coronary artery changes in the elderly patients of coronary heart disease complicated with diabetes mellitus. Methods According to WHO diagnostic standards of diabetes, coronary heart disease(CHD) complicated with diabetes mellitus(65 patients) was indicated as CHD+DM group, and the coronary heart disease without diabetes(68 patients) was indicated as CHD group. All patients were examined by coronary angiographic semiquantitative(CAG), and blood pressure, oral glucose tolerance test, level of blood sugar, insulin, lipid, BUN and Cr were measured. The coronary artery changes were analysed by CAG, and the severity of coronary artery stenosis were evaluated by AHA standards. The related risk factors in coronary artery disease were analysed by pluralism straight line statistics. Results The coronary multivessel changes(75 4% vs 38 2%, P

Objective To investigate the relationship between glucose tolerance change and the coronary artery lesion in the patients with coronary heart disease. Methods One hundred and ninety three patients with coronary artery disease were divided into 3 groups according to WHO(1985) and American Diabetes Association (1997) standard of diabetic diagnoses: (1) normal glucose tolerance (NGT) group 122 cases; (2) impaired glucose tolerance (IGT) group 39 cases; (3) type 2 diabetes mellitus (DM) group 32 cases. All patients were examined by the coronary angiographic semiquantitative (CAG) and 75 g oral glucose tolerance test. Blood glucose, insulin, triglyceride (TG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL C) were determined. The coronary artery changes were analysed by CAG, and the severity of coronary artery stenosis was evaluated according to American Heart Association standard. The risk factors of coronary artery lesion were analysed by pluralism stepwiss regression analysis. Results The coronary multivessel changes and the severity of coronary artery stenosis and calcification were more frequent in IGT group than those in NGT group (66.5% vs 35.1%, 8.9?3.6 vs 6.5?3.9, 6.3?3.6 vs 3.9?4.1 respectively, P

Objective: To investigate the effects of different concentrations of vitamin E (VE) on angiogenesis and its possible mechanism. Methods: The rings of rat aorta were embedded in gels of collagen and cultured in a serum free medium for 28 days. Curves of microvessels growth were generated by counting the number of newly formed microvessels every day with an inverted microscope. Photos were taken at the same time. Expression of factor FVIII related antigen (FVIII RAg) in newly formed microvessels was detected by immunohistochemistry. Concentration change of FVIII R in medium was evaluated by ELISA. Results: Both 0.2 g/L and 0.1 g/L VE showed significant inhibitory effect on angiogenesis (P0.05). The inhibitory effect of VE was expressed in the phases of microvessel growth and decline (10-25 d). Conclusion: 1.Three dimensional collagen gels culture of microvessel in serum free medium can be used as a sensitive assay for study of soluble and solid phase angiogenic agonists and antagonists. 2. Both 0.1 g/L and 0.2 g/L VE inhibit angiogenesis, and VE has no toxicity and no drug resistance.

ObjectiveTo evaluate the clinical efficacy and safety of the traditional Chinese medicine （TCM） compound Chaiqin Xiaoyong Decoction （柴芩消痈饮， CXD） combined with Jinhuang Ointment （金黄膏， JO） in treating the nodular stage of acne mastitis of liver meridian heat accumulation type. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 108 patients with liver meridian heat accumulation type acne mastitis in the nodular stage were randomly assigned to a treatment group and a control group， with 54 patients in each group. Both groups received topical application of JO once daily at a thickness of 3~5 mm for 8 hours， along with standard nursing care. On this basis， the treatment group received oral CXD granules， while the control group received placebo granules， administered twice daily， 3 sachets per dose， for 14 consecutive days. Clinical efficacy， TCM symptom scores， nodule size， visual analogue scale （VAS） pain scores， white blood cell （WBC） count， C-reactive protein （CRP） level， and systemic immune-inflammation index （SII） were compared. At the end of treatment， efficacy and safety indicators were evaluated. A 6-month follow-up was conducted to compare the proportion of patients undergoing surgical treatment. ResultsThe total clinical efficacy rate in the treatment group was 90.38% （47/52）， significantly higher than 32.00% （16/50） in the control group （P＜0.01）. The treatment group also showed significantly lower TCM symptom scores， VAS scores， nodule size， WBC count， CRP level， and SII （P＜0.05 or P＜0.01）. During follow-up， the surgical intervention rate in the treatment group was 5.77% （3/52）， lower than 14.00% （7/50） in the control group， with a statistically significant difference （P＜0.01）. No significant abnormalities were observed in safety indicators before and after treatment in either group. ConclusionCXD effectively reduces nodule size and alleviates symptoms such as redness and pain in patients with acne mastitis of liver meridian heat accumulation type， improves TCM symptom scores， enhances overall clinical efficacy， and demonstrates good safety.
